hey.

how is it possible to print out an array (T_ARRAY) in a C-method?

example

I want to get the instance methods via the corresponding c method. the =
method returns T_ARRAY.
VALUE es =3D rb_class_instance_methods(1, args, CLASS_OF(targetcl));

is there something like:=20
for(int i =3D 0; i<RARRAY_LEN(es); i++)
{
printf("content of array element %s",es[i]);=20
}
?? :)
I know that the content of the array element is a (ruby) string.

thx for your help in advance

rb_ary_entry(n) returns the VALUE at index n.
StringValuePtr(obj) returns a pointer to the C string in a String
object.
